Answer:

Rivers

Explanation:

Water shed is also known as drainage basin and it is a body of land that drains into a body of water.

Rivers are the largest in terms of volume of a watershed. Other watershed examples include lakes, streams and underground water.

The river has more algae and mircroorgamisms in them. These help in converting harmful substances in the water into non harmful useable substances. This process helps in the filtration of the water.

When a virus infects a bacterial cell, often new viruses are assembled and released when the host bacterial cell is lysed. If th

Answer:

D) The virus has entered the genome of the bacterial cell and is in the lysogenic stage.

Explanation:

Virus have two reproductive cycle lytic and lysogenic cycles. In the lytic cycle, the viral genome is expressed using the host molecular machinery and make capsid proteins. These capsid proteins surround the viral genome and make new phages which lyse the host cell and gets released.

After the release, they enter their genome in other host and that genome first incorporates in the host genome and replicates with the host genome. This cycle is called the lysogenic cycle and in this cycle lysis of cell does take place because no new phages are produced in it.

What situation best represents how DNA sequencing, PCR, and gene probes might be used together? Multiple Choice Scientists might

Ivahew [28]

Answer:

Scientists might replicate a strand of DNA using PCR before sequencing it. Once the sequence is known, they can produce a corresponding gene probe

Explanation:

PCR refers to the polymerase chain reaction that amplifies the small sample of DNA into multiple copies in three steps. These steps are denaturation of sample DNA to produce single-stranded template strand, binding of primer to the template and elongation. The multiple copies of the sample DNA are then used to decipher its sequence using various sequencing methods.

Once the sequence of the sample DNA is known, the short, single-stranded DNA molecules that are complementary to the specific sequence of DNA are formed. These single-stranded DNA molecules are called DNA probe and are used to detect the specific nucleotide sequence in some other sample DNA.

The tiles below depict translation events during roughly two cycles of elongation. each cycle adds a leucine (leu) amino acid to

sergij07 [2.7K]

I found the attached image on the internet and I believe it has the tiles referred to on the question.
As we can see on the image, the A-site, P-site, and E-site are represented. The A-site is occupied by the tRNA linked to the growing peptide chain. The P-site is the one occupied by the tRNA that works accepting the growing protein for peptide bond formation.
Firstly, the protein is formed, it is the first tile from the left.
Then, the first tile from the right is where the Leu is formed.
On the second tile from the right the Leu is then added to the protein.
The process is then repeated again as there are two cycles of elongation adding a Leu in each of them: third tile from the right, third tile from the left, second tile from the left.
